future of the war in ukraine. flooding is causing widespread destruction in the west as the swollen mississippi river continues to rise. making matters worse millions across the south are under threat of storms, hail, and even tornadoes. we'll show you who is at greatest risk. and a major win for abortion rights in two republican dominated states. bills restricting abortions failed because a handful of conservatives helped block them. we are following these major developing stories and many more all coming in right here to cnn news central. we begin this hour in ukraine where a vicious new russian attack has killed nearly two dozen civilians. here in the central city, a high rise apartment building was struck by a missile and destroyed. bodies are still being pulled from the rubble but at least 23

are already confirmed dead. that includes four children. officials on the scene expect the number to climb. cnn's nic robertson is live in uman. you arrived at the scene shortly after the missiles struck. how are search-and-rescue efforts going right now? >> reporter: they are still going on, boris. 16 hours now since the missile, what the ukrainian officials describe as a stealth cruise missile slammed into this building. i'll step out of the way and david is going to tilt the camera. look at those firefighters. 16 hours into the mission, they are right up there on the top of the building. they took us up there earlier to take a look and told us they were going to tie ropes on themselves, go off the side there and clear out the upper floors. we know from an eyewitness here that she believes the two daughters of a friend of hers who lived on the 8th floor up there, 13-year-old girl,

7-year-old girl, still unaccounted for. the mother survived. the father is in hospital. but friends and family believe the two girls are up there somewhere. the firefighters are searching through the rubble. they said they would clear the lower floors first. they've done that. now they are moving on to the really hard bit, high up there. as you can see, it is night time here now. it is flood lit but this effort will continue. the massive flood of relief workers, recovery workers, the police even have a dna team here to help relatives identify family members who may be recovered from the building. there are police psychologists here as well. we've seen them counseling some of the grieving families. this happened at 5:00 a.m. here. most people were asleep in their beds. 109 people registered living in this apartment. more than half of the 46 apartments in there just blown apart, destroyed.

this isn't going to stop this evening. the recovery, rescue workers say they'll push through the night until the job is done, boris. >> this is just another example of the many times it appears russians have targeted civilian infrastructure. this is an apartment building not an apparent military target. nic robertson from uman, ukraine, thank you so much for that report. brianna, we are seeing this barrage as ukrainian forces are now putting the finishing touches on their counteroffenses. >> that's right. after months of speculation ukraine's defense minister says preparations for a highly anticipated yoint offensive are coming to an end. military officials have long made efforts to conceal the start of any new military campaign. we have brigadierer general mark kimmitt retired to talk about this with us. you have three key conditions to this counteroffensive being successful. first is that russian forces must decisively byee defeated a ooh nother is key terrain must be seized.

walk us through which areas are most important strategically starting in the east. >> first of all i think it is to decisively defeat the russians and take key terrain, at the end of the counteroffensive they need to end up at a place where they can conduct further campaigns. so not just enough to push them back. they've actually got to sake some areas such as getting all the way here in the south down toward the sea. they have to be able to split that land bridge between crimea, get into pretty much the rear of the russian lines. if they can finish the campaign in that position, perhaps focused on mariupol or areas further south, that would be a significant victory for them. >> then looking at kherson, what do you see here? >> again, this is the area that i think i would be looking at. getting down here, pretty much where the land bridge connects crimea to the donbas, that would

be my area to attack. again, i think the russians are going to expect that, so it is probably the case that is not where they will attack. >> let's talk about if they are ready for this and have everything that they need. at this point you have the head of nato saying 98% of the stuff, call it the stuff they've been promised, has been delivered. walk us through what they have and what position they are in. >> first of all they must have tremendous operational security, because what is coming out in the public domain certainly will not appear that they are ready for this type of counteroffensive. the troops may or may not be fully trained on the combat vehicles. the best is yet to come, the abrams tank for example. this really comes down to the advantage the ukrainians would have over the russians. this would tell me not only they are pretty much ready, but they want to start a counteroffensive

now because they believe the russians will only get stronger so maybe the russians are in their most vulnerable position now. >> this is the abrams tank we're looking at here? >> right. >> this is the leopard tank, which they are more prepared with. they are not expecting the abrams tank in time. what is that going to mean? anything materielly for them you think? >> when you have an offensive you want to quickly punch through the tough front lines of the enemy. this is probably one of the better weapons systems along with their artillery that would be able to break through the russian lines and push deeper into those objective areas we were talking about. >> all right. we'll be watching. this could be a very pivotal moment. general, thank you so much for taking us through that. here at home in parts of the midwest the snow is melted and so the river is rising. experts warn the snow melt could cause some of the worst flooding along the upper mississippi in 20 years. have a look at davenport, iowa.

flood waters there have already swallowed much of the river front area and the threat they say could linger for weeks. cnn meteorologist chad meyers has been covering this. walk us through the concerns. a lot of snow. heats up. a lot of water. >> it heated up quickly. and the snow melted rapidly. didn't even see flash flooding with rainfall. this was literally all snow melt. started up here in the north, minneapolis. now finally coming down a little bit. but the bubble of water is headed down river into other bigger cities. notice what this bubble looks like. it is a flat line going up slowly. most of the time we show you flash flooding. it looks like this. because it goes up very fast. that is the flash part. this is a river flood. and just because the current level is 20 feet and a little bit higher in davenport doesn't mean there is 20 feet of water anywhere except in the bottom of the river it's 20 feet higher than what the army corps of

engineers say this is where the river should be. 20 feet higher than that. a lot of the town is well above 15 or 20 feet higher than the river should be. so this isn't widespread. it is in second floor building. it is not like that. the river spreads out. the mississippi river is very, very wide. that's the reason it is so fertile because this river has been flooding for hundreds of millions of years. that ground there is so very fertile that is why we grow things on it because it floods, gets nutrient, and grows things. now we are getting these floods into places where people live. >> it gives, it takes away. all right. moving further south, lots of red in the southern part of the country around texas. what's happening? >> there will be another severe weather event today. maybe not quite as bad as wednesday. that was just enormous hail. right now not seeing anything on the radar.

it is sunny. that is part of the problem. we'll get thunderstorms up in this area and hail 2 to 3 inches large. this is what fell on wednesday. that is a guy's hand right there. this was 3-inch hail. that is a possibility today from texas, dallas all the way down to waco. this is only a couple hours from right now. right now the radar blank. this is going to fire up. this is really a hail and a wind event for today. it moves to the east and it even moves into florida for tomorrow. there could be some strong weather there as we work our way into your saturday afternoon. >> we know you'll be watching. thanks so much. boris? as republican led states across the country push bills cracking down on gender affirming care and abortion the governor from the key swing state of minnesota has signed bills protecting those rights. he is going to join us live, next. and in alaska a tragic accident during an army training

abortion rights supporters are celebrating a pair of unexpected victories today after lawmakers in two republican dominated state legislatures failed to pass bills severely restricting abortion access. in nebraska some people were moved to tears after the so-called heart beat act failed by a single vote. in south carolina, senators rejected a bill that would have banned nearly all abortions in that ruby red conservative state. in both cases it was key republican lawmakers that opposed their own party's proposition for new restrictions. in the last hour a south carolina republican senator told me the fight for middle ground is her main focus. >> i do not think we have a right to abortion, but we may not have a right but it is the reality, and i've always said it needs to be legal, safe, and rare, really rare. but there's got to be some gray

area. because life is not simply black and white. i recognize that. over 70% of south carolina recognizes that. most of us feel in our state there should be restrictions. so it is just reaching a happy middle or at least a general consensus among the bodies and the south carolina house will not accept our stance, the senate. >> in minnesota lawmakers took a proactive approach to protecting up abortion. the state's democratic governor signed new legislation further preserving the right to abortion. governor tim walls signed a new lawmaking access to gender affirming care a position in the, forgive me, making that a law. he also passed a bill protecting or rather going against conversion therapy for gays in minnesota.

minnesota governor tim walz joins me now. forgive me for that confusion. we appreciate you sharing part of your afternoon with us. you made abortion a central issue in your campaign. it helped you win re-election. why was this a top priority? >> well, thanks for having me, boris. i'm glad to see in south carolina and nebraska they are trying to moderate but it isn't all that complicated. the reason we made it central is it is a basic human right that people have the right to make their own healthcare decisions. let's be clear. abortion services are health care. gender affirming healthcare is healthcare. the idea of trying to split the hair or decide government should be involved with that is simply not the way it is. here in acetaminophen we are watching this hate and bigotry all around us, in the dakotas, in iowa, and we've decided we'll be an island of decency and trust people to make their own decisions. it is important now more than ever to firewall up the laws. we know what the supreme court is doing and will continue do and we want to make sure folks

know you come here, you are protected, these are your decisions. >> governor, you describe your decision and the new law as making minnesota an island of decency. several states around you placed severe restrictions on abortion. you are seeing an influx of patients in your state seeking care. are you concerned at all that might strain resources? >> well, it will. they make it more difficult and we know reproductive healthcare is something that is absolutely critical. we are seeing in states that are passing these laws they're having a difficult time. my announcement and signing ceremony yesterday, we had a physician from wisconsin call herself a refugee because she is now performing the duties that she needs to do in rural minnesota where she is protected and able to do it. yes, it will strain resources but we'll continue to put more resources into that. this is something that has ban right in this country for 50 years. i'll disagree with the legislator from south carolina. it is a right, a basic human

right, and extends across the spectrum and is not government's decision to -- i hear these governors talk about freedom. freedom to be in the exam room, freedom to be in your children's locker room. freedom to be in your bedroom. that is not what we believe in minnesota. now more than ever we need to take that proactive message and push back on this. people's lives are at risk. healthcare is being compromised. we know the impact. these folks are just bullying folks who are the most vulnerable for a political end spending time and money on bathroom bills. it is ridiculous. we're trying to create jobs, move to a clean energy economy, and we'll shore up these basic protections. >> governor, on that note the supreme court could potentially make a decision, take up a case on the most commonly used abortion pill in the country, mifepristone. does that speak to you that there should be an urgency among lawmakers in congress to enshrine abortion as a right?

>> absolutely, boris. we are worried about it. we're trying to stock up the best we can. minnesota is home to the mayo clinics and the best healthcare in the world. all of the professional medical associations agree with this on the gender affirming care, abortion, they agree on access to these drugs. so they absolutely should. we absolutely know when someone tells you who they are, believe them. the supreme court has told us who they are. yes, i think there is a real sense of urgency. we're feeling it here and continuing to do everything we can proactively, knowing that we're seeing states around us. again, those women and those individuals least able to travel or get this care are going to be put at risk. and for what? for a demonization and short-term political gain. these are people that never thought about bathrooms or transgender children until they decided there was a political gain for them. we'll make it very painful.

you are seeing it in nebraska and south carolina. you either come around to where the vast majority of people with decency and compassion live or face consequences at the ballot box. that is a good thing. >> governor, as this law was still in its early stages, republicans described it as too extreme. they try to promote a number of amendments specifically around late-term abortion that you rejected. is that something you might reconsider, late-term abortion isn't very popular. >> it's a straw man. it doesn't happen, boris. those are cases when those types of things happen it is because a decision was made to protect the woman's life to make sure those decisions are made by healthcare providers. they know that. they know the incredible rarity of these situations. it is not as if someone is making these decisions based on just a late decision they didn't get around to making. that is nonsense. they continue to split hairs. the extreme position is what you saw in north dakota no exceptions for rain or incest. six weeks when most women don't know they're pregnant. and putting people at risk.

i just reject in its entirety that we know who the extremists are. we know who are telling that. the american people overwhelmingly know that. i just think the biggest thing here is we think here in minnesota calling that out, going offer the offensive, and, look. this is not anything special. what's happened in minnesota now is individuals will make their own healthcare decisions based on what all of the evidence and all of the practice among all of the major medical providers agree is the right way to go. that is the only thing we did here. if there is an extreme position, you're seeing it. it is all around us. >> governor, on the new law protecting gender affirming care, what do you say to folks that argue, that puts minors at risk? >> well it does not. what puts minors at risk is elevated use of suicide and not having the care. the american pediatric association, american psychiatric association, providers across the country and world understand that these are things that need to be affirmed

to. once again, they send out graphic videos, just that are things that do not happen that again are decisions being made by parents, by individuals that are really trying to figure out only how they can have a place to live in the world and just live who they are. again, they will not report the facts. they will not listen to the people involved in this. i would just say this. these are the folks telling us it puts children at risk. they all voted against providing meals for kids in school here in minnesota. i've kind of lost patience with oh, this puts kids at risk. these are folks that aren't interested in doing gun legislation. they're not interested in providing meals or health care to every child which we're doing on all of those fronts. so again, these are arguments as old as time. they are not going to work anymore. protecting our children is not a second amenitiment issue but a safety issue. you can protect and have

firearms at the same time you protect your children. i reject that argument. >> governor walz, thank you so much for the time. we appreciate the conversation. >> thank you, boris. >> of course. jim? the cdc is now investigating a rare and mysterious cluster of brain infections in kids. we'll show you what to look out for and what could be behind this. mayor eric adams of new york is pleading with fema to stop giving money to cities that are then using those funds to send migrants to new york city. ahead, what more he is asking of congress and the biden administration. more than 10 0 ye. from the most advancnced technology to the broadest, most reliable network of sales and service dealers. we lead. others follow.

a wave of russian missiles hit ukraine overnight in what could be the deadliest attack on civilians in months. in the city of uman more than 20 people were killed including children when a missile hit this apartment building just taking off the entire corner as you can see here. in a video provided by a ukrainian official you see the aftermath of the strike. we want to warn you this video is graphic. >> i never thought this would happen. a rocket hit our building. we are all covered in blood. i don't know. our windows were blown out. this is the room where children were sleeping. it is good we are all alive. we are just all covered in blood. god we don't have windows. nothing. i was so afraid. >> the death toll is likely to rise as rescuers continue to search through the rubble. back here in the u.s., utter devastation in the florida panhandle outside tallahassee after a possible tornado. roofs ripped off, personal

belongings scattered everywhere. today more than 50 million people across the south and the mid-atlantic are under severe thunderstorm threats with tornadoes possible as well, boris. we are also watching a disturbing trend increasingly affecting kids in nevada. the cdc is investigating a cluster of serious brain infections, which include pus-filled pockets known as brain abscesses that seem to be growing at an alarming rate. cnn's senior medical correspondent is now live with more. elizabeth, walk us through the symptoms. what are they seeing? >> reporter: doctors in clark county, nevada, boris, were seeing more children than they're used to seeing. this is an unusual event. let's take a look at what the numbers say. before covid, they were seeing about four cases of brain abscesses, infections in the brain in children and then when they looked in 2022 it was 18. so they saw the numbers go up and up during the pandemic.

and those numbers again still very strong. there is no other documentation of this happening in other places in the u.s. but doctors do in other places tell cnn sort of anecdotally they're seeing more of these. these are infections that can often start, say, in the mouth. maybe sort of the child has a cavity or something like that or a sinus infection and that can sometimes travel into the brain. boris? >> so, elizabeth, what is causing this? >> reporter: you know, some people have a theory it is because for a period of time during covid children weren't in school. they weren't being exposed to germs the way they usually are. now their defenses are lower. i've been speaking with experts who say, actually one said ridiculous. that was how they described that theory. they are saying is it possible? sure. anything is possible. they think there are other explanations here. first of all, remember this is just one county. this could just be a blip. but in addition there could be other things going on. for example, during covid maybe

children got covid and then they got these secondary infections. there are all sorts of yeens this could be happening. boris? >> it is certainly potentially a statistical anomaly but concerning, nevertheless. thanks so much for that. the migrant crisis has repercussions far beyond the southern border, extending to many cities notably democratically run cities including new york. mayor adams is calling on fema to stop sending money to cities and states that are using the fema funds to then bus migrants to cities like the big apple. he is calling on the biden administration to step up before covid era border restrictions end next month one of the ironies here, you have these states doing this certainly with politics in mind using federal money to drop those migrants. we've seen it here in d.c. outside the vice president's house. we've certainly seen it in new york. what does he want done?

>> reporter: jim, this certainly has potential to lead to a thorny relationship between new york city's mayor and president joe biden. the mayor has really been amping up the pressure on joe biden to step in and help. new york city shouldered the mounting cost of addressing this asylum seeker crisis in new york city for the last year already and still seeing about #it 00 arrivals a day -- still seeing about 200 arrivals a day. we've seen 58,000 arrive since last spring and out of those numbers about 36,000 are still being cared for by the city of new york. talk about a major price tag. i obtained some of the documents submitted from new york city's government to fema trying to get their hands on some of the -- or at least recover some of their funds. they are still paying roughly $383 a night per household. we should say household typically would be a family unit. it is not necessarily individuals. but that is $383 a night for an average of 7,000 households per

day. that is millions of dollars that the city is out. what we've seen recently is eric adams amplifying that and calling on the president to step in and assist in the form of expanding temporary protection status to include central america, venezuela, sudan, as well. and, also, to increase u.s. cis personnel to deal with some of the work authorization requests. as you are about to hear from mayor eric adams he feels not just abandoned by republicans in congress but his fellow democrat in the white house. here he is. >> greatest challenge is the migrant and asylum seekers. the republican party's failure to come up with real immigration reform is going to devastate this country and the white house not having a real plan i think is irresponsible. the lack of funding is going to undermine this entire city.

>> we should mention cnn has reached out to the white house for comment, jim. as we wait to hear from them, it is important to really just underscore that very direct language from eric adams recently saying this crisis is, quote, decimating the foundation of new york city if the government does not step in to help. >> of course this is happening with a city of new york which already has a homeless problem as well. thanks so much. brianna? jim, one of the surviving roommates in the university of idaho murders agreed to speak with alleged killer bryan kohberger's attorney. what this will mean for the case moving forward. a close call for two brothers in texas after a lightning strike. we have their miraculous story, still to come.

in alaska three u.s. soldiers have died during a training exercise after two apache helicopters collided. both were returning to fort wainwright near fair banks. the victims' names have not been released as the pentagon is notifying their families. this is the second deadly helicopter crash during an army training mission that we've seen in the past month. cnn's natasha bertrand is a the pentagon with more. what are you learning about this accident? >> reporter: brianna, the army is still investigating this accident, but what we are told from the army's 11th airborne division is that the helicopters did collide in mid air when they were coming back from a training exercise in alaska, flying near healy, alaska about 100 miles south of fort wainwright and the crash occurred about 200 miles north of anchorage to give you a

sense of where it occurred. we are told that three of the service members aboard the helicopters out of the four were actually killed in the crash and the fourth soldier is receiving treatment for his injuries at a hospital there. but still under investigation how this happened, why this happened, and of course as you noted this is the second time in under a month that there has been a helicopter crash, military helicopter crash. the last one occurred in kentucky and nine u.s. service members were killed in that accident. the u.s. military says they are not releasing the names of these deceased until after, 24 hours after the families have been notified, but, sadly, this is not an uncommon event. >> certainly not here recently especially. thank you very much. a very sad day. boris? now to some of the other headlines we're watching for at this hour. florida governor ron desantis is moving to shield himself from the intense media scrutiny that would come with his expected

2024 presidential run. the state republican party is pushing through a bill that would conceal information about his travel and meetings and he is exerting executive privilege in court to block staff testimony and the release of records. now, that may sound familiar, but it's never been asserted by a florida governor before. a man hunt is still under way for two of the four men who escaped a mississippi jail over the weekend. cory harrison and casey grason are still on the run. jerry raines was captured yesterday in texas. dylan arrington was confirmed dead after a fire broke out as he was barricaded inside a house and engaged in a shootout with police. a texas woman's two boys were playing outside when they were struck by lightning. 7-year-old isaac martinez and 13-year-old jaden alvaredo both collapsed and lost consciousness when it happened on wednesday but miraculously the brothers survived. they are expected to be okay. their mother understandably,

though, was overcome with emotion. listen. >> it is a blur. i just remember everybody praying and telling them, jaden, isaac, come on. come on. breathe. breathe. you have to wake up. wake up. i thought i had lost my boys honestly. it's the worst feeling ever. and now, thank god every second that he didn't take my boys. >> understandably shaken up there. jim, glad they're okay. now they have a cool story to tell. >> lord, so close. happy for the family. well, another story we're following, a legal fight has ended at least for now in just a horrible, quadruple murder case that has engrossd so many of us. you may remember the four university of idaho students stabbed to death in their off campus home. you'll recall about a month later police arrested a

28-year-old, bryan kohberger a grad student in criminology. now a roommate has agreed to speak with his attorneys after she initially resisted their request to testify at kohberger's preliminary hearing which is coming up. cnn's jean casarez has been covering the story. can you explain what is behind the kohberger team request to speak to this roommate? >> reporter: you know, this is fascinating. we don't know what the defense believes they had. we have to look at the legal documents. here is what they say. the defense investigator in a sworn affidavit sworn under penalty of surgery says bethany funk had numerous interviews with law enforcement, that she was at the home hooeight hours later when law enforcement arrived after the murders happened but during the course of my investigation, he says, i have uncovered information that

is material, key word, material to the defense of brian kohberger. the judge in idaho must know what it is because she did the extraordinary measure at this stage of the proceedings of issuing a foreign subpoena to the state of nevada to a judge asking a judge to compel her attendance in idaho to testify for the defense during the preliminary hearing. that is in june. well, bethany funke got an attorney and she didn't want to do that. so bethany funke we do know was in the house. she was on the first floor. everybody else was on the second and third floor. and she now has reached an agreement the chief public defender will fly to nevada to interview her. but, jim, this is interesting because she is going to have an attorney by her side. that attorney will try to protect her. she may not want to answer these questions. the attorney may agree. so will this be over or will this continue? >> just to be clear here, it is

not just the defense team that is making this argument that her testimony is necessary. the judge had to in effect approve that demand. >> that is exactly right. that is what takes this to a level that you have to make a pause and say, what is it that the judge believes is so critical at this point? because normally a judge would say, you know, a the trial you can put her on as a defense witness. you can question her. but this is before the case is even bound over for trial. >> understood. jean casarez, thanks for filling us in. can artificial intelligence help police departments evaluate officers in the field and prevent cases of brutality? cnn got a first-hand look at the new technology being tested across the country. you'll see it for yourself when we come back. that makes you feel lighter than air? ♪ no matter r where you are... when it crosses your path...

artificial intelligence can help write essays, create images, and even drive you around. an can it also help improve policing? that's what departments across the country are trying to find out. they're using ai technology to evaluate officers in the field. cnn got to see how this technology works firsthand. >> reporter: this officer is on patrol. he has all his tools for the day, including his body worn camera, which automatically captures videos of his encounters with civilians. >> you first. >> absolutely. >> reporter: 20 videos a day, over 100 hours a week. his final invisible piece of

equipment, artificial intelligence. a program called trulio, which analyzes what he records. >> did you have fears about what it meant to have artificial intelligence tracking your day-to-day? >> i did have apprehensions. it is ai. technology can sometimes have drawbacks. it's not perfect. but at the same time, i've seen stuff play out enough that technologies have helped us. >> reporter: and that's what the founder is hoping for. >> we started trulio after george floyd was murdered in 2020. >> what percentage of body camera footage gets reviewed now? >> a fraction of 1%. >> and trul yo could look at what percentage of body cam video? >> 100%. >> reporter: the ai was trained by humans to detect 5 million key terms, like profanity, non-compliance, as well as

professional language or explanation. the goal is to detect early problematic police behavior before it turns deadly. dan's chief, ken troofr in pennsylvania, has been using trulio for a year. he's also an adviser. >> these are the keywords you put in. >> they are. stop resisting, custody, arrest, anything to do with pursuit. >> reporter: trulio transcribed entires -- but pinpoints moments that need review. >> stop resisting. just relax. >> not a whole lot of resistance, but it was giving me exactly what i was looking for. >> for you, this is a good interaction with one of your officers is a civilian. >> it is. >> reporter: the alameda police department in california has been using trulio for a little over a year. it's seen a 36% drop in use of force by officers. the ai pointed out risky interactions with civilians

giving officers the chance to review and change their behaviors. >> what would trulio's involvement have been in a situation like tyre nichols? >> i feel very strongly that trulio not only would have recognized the event of the murder of tyre nichols but the hundreds of events that took place prior to that. i believe trulio would have prevented the death of tyre because it would have detected deterioration in the officer's behavior years prior. >> reporter: there are 18,000 police departments in the u.s. just 20 are using trulio, with 20 more signing on this year, including aurora p.d. in colorado. >> it will be an early warning system that will help save careers and lives. >> reporter: in 2019, three aurora police officers were charged with the death of elijah mcclain, using excessive force during his arrest. >> we see just a little change in the officer's performance,

we'll be able to actually intervene early on, get them help, get them counseling, get them training, do whatever it takes to get back on the right track. >> reporter: back in castle shannon, chief trooper says the technology has only proven what he already suspected about his officers. >> what has this changed, anything? >> no. and i don't think that's a bad thing. i want to catch something before it happens. i don't want to be reactionary. we want to be looking ahead to make sure that we stay ahead of the game, ahead of any issues. and i don't think that's a bad thing. >> reporter: and the seattle police department was the first department to start using trulio, but they have since cancelled their membership with trulio because they say they have concerns over citizen privacy. but trulio says that all citizen privacy data is stored where it's always been stored, and that is on the police department's servers.

and boris, another barrier to entry for some of these police departments may be cost. it's about $20 to $50 per officer per month. if you have 100 officers, that's about $60,000. so, some departments may have a tough time paying for this. but there are federal grant programs in place. boris, ultimately time will tell. body cams were slow to be adopted by police departments, but they're common practice now. we shall see if this artificial intelligence is accepted ultimately in the same way, boris. >> it is incredible technology. thank you so much for that report. jim? three teens now face charges for throwing rocks at people in their cars, ultimately killing a woman. new gruesome details just discovered by investigators coming up next on "cnn news central." starting witith the sound system...
